Proper fix for disabling warnings in read_statistics_for_table().
MDEV-20589: Server still crashes in Field::set_warning_truncated_wrong_value
- Use dbug_tmp_use_all_columns() to mark that all fields can be used
- Remove field->is_stat_field (not needed)
- Remove extra arguments to Field::clone() that should not be there
- Safety fix for Field::set_warning_truncated_wrong_value() to not crash
if table is zero in production builds (We have got crashes several times
here so better to be safe than sorry).
- Threat wrong character string warnings identical to other field
conversion warnings. This removes some warnings we before got from
internal conversion errors. There is no good reason why a user would
get an error in case of 'key_field='wrong-utf8-string' but not for
'field=wrong-utf8-string'. The old code could also easily give
thousands of no-sence warnings for one single statement.
